36958
MD number
$MA_SAFE_ACCEPTANCE_TST_TIMEOUT
Time limit for the acceptance test duration
840D
Default: 40 Min. input value: 5 Max. input value: 100
Change becomes effective after POWER ON: Protection level (R/W) 7/2 Unit: s
Data type: DOUBLE Applies from SW 6.4
Meaning On the NCK side, a time limit can be specified for the duration of an acceptance test
(there is a drive machine data MD 1358 that corresponds with this, in which the same time
must be entered). If an acceptance takes longer than the time specified in MD 36958,
then the NCK terminates the test. The acceptance status is set to zero on the NCK side.
If the acceptance test has been reset, then on the NCK and drive sides, SI POWER ON
alarms are again changed-over from being able to be acknowledged with a reset to being
able to be acknowledged with a POWER ON.
NCK clears Alarm 27007 and the drive, Alarm 300952.
This MD is also used to limit the duration of an acceptance test SE. After the program
time has expired, the acceptance test SE is interrupted and Alarm 27008 is cleared. The
software end positions are then again effective the same as they are used in the machine
data.

36960
MD number
$MA_SAFE_STANDSTILL_VELO_TOL
Shutdown speed for pulse cancellation
840D
Default: 0 Min. input value: 0 Max. input value: 1 000
Change becomes effective after POWER ON: Protection level (R/W) 7/2 Unit: mm/min, inch/min, rpm
Data type: DOUBLE Applies from SW 3.4
Meaning When the axis/spindle speed drops below this limit, it is considered to be at a "standstill".
In STOP B mode, the pulses are then cancelled (through transition to STOP A).
Corresponds with … MD 36956: $MA_SAFE_PULSE_DISABLE_DELAY
36961
MD number
$MA_SAFE_VELO_STOP_MODE
Stop response, safely reduced speed
840D
Default: 5 Min. input value: 0 Max. input value: 14
Change becomes effective after POWER ON: Protection level (R/W) 2/7 Unit: -
Data type: BYTE Applies from SW 3.4
Meaning The ones position defines the selection of the stop responses when the safely-reduced
speed is exceeded.
The tens position defines the behavior when the drive bus fails if a time greater than 0
was parameterized in $MN_SAFE_PULSE_DIS_TIME_BUSFAIL.
Special case: For a value of 5 in this MD, the stop response for each SG stage is
selectively defined $MA_SAFE_VELO_STOP_REACTION.
=0: Stop A
=1: Stop B
=2: Stop C
=3: Stop D
=4: Stop E
=5: SAFE_VELO_STOP_MODE invalid, the stop response is parameterized using
MD.
SAFE_VELO_STOP_REACTION Stop A, in addition when the drive bus
fails and the SG is active, the pulses
are not immediately cancelled
=11: Stop B, in addition when the drive bus fails and the SG is active, the pulses
are not immediately cancelled
=12: Stop C, in addition when the drive bus fails and the SG is active, the pulses
are not immediately cancelled
=13: Stop D, in addition when the drive bus fails and the SG is active, the pulses
are not immediately cancelled
=14, Stop E, in addition when the drive bus fails and the SG is active, the pulses
are not immediately cancelled
